WINDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 792,565, dated June 13, 1905.

Application filed June 4, 1904. Serial No. 211,204.

To all 1072,0721, it may concern:

Be it known that I, SIMON WV. WVARDWELL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in inding-Machines, of which the following is a specification.

My invention relates to winding-machines, and particularly to that class of machines in which the thread-guide bears at all times during the winding on the surface of the cop, receding from the Winding-spindle as the yarn is built up thereon.

The object of my invention is to provide improved devices for preventing the guide from returning toward the winding-spindle after it has been forced out by the growing cop.

The invention is fully set forth in the following specification, illustrated by the accompanying drawings, in which Figure 1 is a front View of the winding-machine; Fig. 2, a detail of the traverse-frame detent, being a sectional view on the line 1 1, Fig. 1; Fig. 3, a detail of the detent fingerlever, showing its relation to the traverseframe.

The machine in general is of a familiar type known to those versed in the art as the Universal W inding-Machine. It comprises, essentially, the main frame A, supporting bearings for the winding-spindle B and cam-shaft O, the latter carrying the cam (not shown) which reciprocates the thread-guide D. The thread-guide slides in the traverse-frame E, which is pivoted on the cam-shaft G and adapted to swing to carry the guide away from the spindle. The traverse-frame carries a weight E below its pivot-point which serves as acounterbalance for the frame and the mechanism it carries. In order that the cop may be wound hard and iirm, it is necessary that the guide bear at all times upon the surface of the cop, and to provide for this pressure is applied to the traverse-frame to resist its movement outward from the winding-spindle. For this purpose I prefer to make use of the devices shown at G and described in my pending application, Serial No. 135,768, filed December 18, 1902,

in which the weighted arm a is connected to the lower arm of the traverse-frame and tends to swing the latter to carry the guide toward the winding-spindle.

The cop-tubes employed for winding-machines are generally formed of paper or straw board made inexpensively and apt to have rough irregular surfaces. If the thread-guide were allowed to follow in and out over this wavy surface in traversing the tube, the cop would be started with an irregular foundation and the irregularities would be magnified as more layers were added. Also in the style of winding effected by this variety of machine the coils of thread cross and recross each other, and at each crossing one coil is raised above the other, so that the guide is pressed outward beyond the plane of the original coils in any one layer. The in-and-out movement of the guide from this cause, if allowed, would also tend to accentuate the irregularities of the cop-surface; but it has been determined in practice that if the guide is prevented from returning toward the spindle after being once forced outward the surface of the cop is maintained straight and regular during the Winding. Various devices have been heretofore designed to adapt the guide to reciprocate always in a straight path parallel to the surface of the winding-spindle; but my improved means accomplishes the desired result with a simple and positive mechanism.

The operation of the machine is controlled through a starting-lever J, which when shifted to start the winding is held in position by the detent H. This latter is formed as a sector, pivoted at 72. and supported concentric with the axis of the traverse-frame E by the extension It, bearing on the arm Z of the lever J. On the under side of the sector H is a V- shaped groove 9, extending throughout its entire length. (See Fig. 2.) Extending parallel to the back of the traverse-frame and supported in bearings in the lug f and leg 6 of the frame is a rod 6 formed with a detentarm 0, bent at right angles thereto and having an extension 6, tapered to correspond to the groove 9. At the outer end of the rod is fastened a finger-lever 7", bearing against the lug and serving to retain the rod in its bearings. Thelever f is preferably made of sheet metal, with a portion formed to surround the rod 0' and adapted to bind upon the latter when clamped with the screw 7. Adjacent the top of the lever is fastened a double wire spring a by means of a rivet a. \Vith the lever properly adjusted the spring a engages a portion of the frame E, tending to carry the lever outward and forcing the extension (2' of the detent firmly into the groove 7. Any tendency of the frame to move backward toward the winding-spindle is resisted by the wedging of the detent in the groove; but the outward movement of the frame tends to swing the detent, and thereby releases its hold on the sector. Ilt will be seen that the frame swings readily outward under the pressure of the growing cop on the guide, and its movement is only resisted by whatever pressure is applied through the devices at (r. The inward movement of the frame, however, is prevented by the detent 0 unless the latter is released by the operator.

In removing knots, &c., and in piecing the yarn the operator frequently moves the traverse-frame outward as far as possible to make room for his hand between the guide and the package. hen it is desired to resume the winding, the guide is readily returned to the winding-spindle by pressing upon the lever f to release the detent from the sector. It is important, however, that the guide shall not be pressed against the package with too much force or the latter might be injured by careless operators. To guard against this, I provide an arrangement whereby the movement of the frame is under perfect control of the hand upon the operation of the finger-lever. To this end the back of the frame is formed with an extension 0, (see dotted lines, Fig. 3,) which besides serving for the spring s to bear on provides a convenient grasping place for the operators fingers. The most natu ral manner of operating the lever f will be with the thumb bearing against the portion a" and the forefinger pressing on the lever f. In this way agrasp of the traverse-frame itself is insured, and it is then under easy control of the hand and may be moved at will to adjust the guide delicately against the package.

It will be seen that the devices above described are an improvement over any now in use, having the advantage of extreme simplicity, positive action, convenience of operation, and least liability of being impaired through wear.
